OIL-BURNER.

Specification of Letters Patent. Patented Oct. 22, 1918.

Application filed June 24, 1918. Serial No. 241A57.

To all whom it may concemap Be it known that I, GRAIBTVILLE A. HU- MASON, a citizen of the United \States, residing at Houston, Harris county, TeXas, have invented a certain new and useful Improvement in Oil-Burners, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to oil burners and has particular reference to a novel means of spraying oil, or a combination of oil with air or steam, or both air and steam, for the purpose of burning in a furnace.

One object of my invention is to provide a means of spraying the oil whereby the oil. will be atomized in contact with air and steam in such manner that the most complete combustion of all oil p2ll'tl"l: w ll take place.

Another object is to provide an efiicient chamber for properly mixing the oil with sprayed for burning.

Another object is to provide means of regulating the amount of oil discharged and at the same time to regulate the fineness of the spray.

Another object is to so construct the burner as to permit of convenient disassembling of the parts for cleaning or repair.

Other objects and advantages will more clearly appear inthe specification which follows. 7

Referring to the drawing forming a part of this specification, and wherein like numerals refer to like parts throughout the several views; Figure l is a side view, partly in section on line 11 of Figs. 3 and 4, of one embodiment of my invention; Fig. 2 is a top plan view of the mixing chamber of my improved burner; Fig. 3 is a similar view, partly in section on line 3-3 of Fig. 1 and with'the air regulating means removed;

' Fig. 4 is a top plan of the oil heating chamber; Fig. 5 1s a view similar to that shown in Fig. 1, illustrating a modified form of nozzle for the discharge of the oil; Figs. 6 and 7 are views similar to Figs. 3 and 4 but showing the embodiment illustrated in Fi .5.

n the practice of my invention I have contemplated projecting steam and oil into a chamber where they will be mixed intiwhat and flattened at the mately in combination with air and forced outwardly through a nozzle in atomized and partly gaseous condition into contact with the fire and thus produce complete combustion. The oil is given a preliminary heating by contact with the steam pipe before entering the mixing chamber and the steam itself is superheated. In Fig. 1 I have shownthe steam-pipe 1, leading from a steam boiler and superheater, not shown, through a small thereby heated somewhat. From this chamher it is conducted under I pressure through pipe 6 to a nozzle 4 in the mixing chamber 3. The two nozzles 4 and 7 are preferably made in one integral casting shaped as shown i" the drawing. into an opening 8 in said chamber and has lateral flanges 9 thereon by means of which it overlaps the margins of said opening and is secured in place by screws 10 or other similar means upon said chamber 3. The

two integral nozzles 4 and 7 are arranged to converge- -at the point of exit into the chamber 3. The oil issues from the nozzle 4 into the mixing chamber 3 through fine openings in 11 inc, fan-shaped spray in the same manner as' does the steam.

I Air finds an inlet into the mixing chamher through sector shaped openings 13 in the top of the chamber. Pivoted rotatably upon the top of having openings therein adapted, when properly adjusted, to register with the openings 13 in said chamber. A small thumb screw 15 serves to retain said valve in adjusted position. By means of this valve the D chamber may in an obvious amount of an supplied to said be regulated as desired The mixing chamber 3 is widened somethereof, as shown at 16, and has a' series of! small openings 17 through which the oil and steam are projected in atomized condition into the furnace. The mixing chamber is adapted for placing at a point justinside The 70 This casting fits 80 said chamber is a valve slide 14, 95
